  • Object of the present invention is therefore to avoid the disadvantages of known fasteners described and to propose a method for the design of a contact surface and a mating contact surface of a connecting element, in which the compression load can be kept substantially constant and in particular voltage peaks in the edge regions of the contact surfaces are largely avoided.
  • Another object is to increase the fatigue strength of the connecting element substantially and to avoid fatigue fractures.
